Few scientific reports regarding the success of complete mouth partial fixed dental prostheses frameworks fabricated with zirconia are available, especially when dental implants serve as the abutments. A complete mouth reconstruction with zirconia frameworks veneered with feldspathic porcelain is reported involving a 65-year-old white woman who presented with partial edentulism and an unrestorable remaining dentition. After examination, 14 implants were planned (8 in the maxillary arch and 6 in the mandibular arch), and implant-supported zirconia framework screw-retained partial fixed dental prostheses (ISZPFDPs) were fabricated and made in sections for easier retrievability and management. No major complications were encountered during follow-up appointments at 6-month intervals for 4 years. However, minor fractures of the veneering ceramic were noted 4 years after placement. The ISZPFDPs were well accepted by the patient and had a favorable outcome in terms of patient acceptability and success, despite some complications.
关于用氧化锆制作全口局部固定义齿支架成功的科学报告很少,尤其是当牙种植体作为基牙时。本文报告了一例用长石质瓷贴面的氧化锆支架进行全口重建的病例,患者为一名65岁的白人女性,存在部分牙列缺损且剩余牙列无法修复。检查后,计划植入14颗种植体(上颌弓8颗,下颌弓6颗),并制作了种植体支持的氧化锆支架螺丝固位局部固定义齿(ISZPFDPs),并分成若干部分制作,以便于取出和管理。在4年中每隔6个月的随访预约期间未遇到重大并发症。然而,在放置4年后发现贴面陶瓷有轻微骨折。尽管有一些并发症,但ISZPFDPs被患者很好地接受,在患者可接受性和成功率方面有良好的结果。
